I don’t believe these are huge features, its OSM building for the
world. Must be the memory constraint since it is a lot of features.
This doesn’t happen (i think, am retesting now) if created from the
osm pbf file directly but does from the fgb created from the pbf.
Hum, it might be that the FGB reader is a bit gready in its memory usage
then. Björn might be able to comment more
Do either of the columnar formats (arrow, geoparquet) support spatial
access window selections yet (via ogr2ogr) or is that still forthcoming?
There is no spatial index specification for those formats (yet ? it
isn't obvious how to stick one into them, in a clean and backward
compatible way, but I believe this is a subject of research). So for now
spatial filtering involves scanning all features geometries (there are a
few optimizations to make it as efficient as possible, but you
definitely won't get a great performance if repeatedly selecting small
amounts of features with different extents)
